Dear CloudRouter users,
Following the support for Claude Opus 4.7 on the x4 Official Premium Channel and the x6 Official Flagship Channel, the adaptation work for the x2.5 Smart Selection Channel has now been fully completed. Claude Opus 4.7 is now fully available across all three channels, and you can freely choose based on your business scenario.
1. Channel Support Overview

3. How to Use
Claude Code users: Run /model in the corresponding channel and select Opus 4.7. If this option does not appear in the list, please upgrade Claude Code to the latest version and try again.
API users: Set the model name to:
claude-opus-4-74. API Parameter Differences (4.6 → 4.7)
Switching from Opus 4.6 to Opus 4.7 involves breaking changes. Please complete the parameter adjustments before calling, otherwise a 400 error will be returned. The following is for reference only; the official Anthropic migration guide is authoritative.
| Item | Opus 4.6 | Opus 4.7 |
|---|---|---|
| Extended Thinking | thinking: {type: "enabled", budget_tokens: N} | Must be changed to thinking: {type: "adaptive"}, with thinking depth controlled via output_config.effort (low/medium/high/xhigh/max) |
| Sampling parameters | Supports temperature / top_p / top_k | Non-default values not supported; must be removed from the request |
| Thinking content display | Returns summarized output by default | Omitted by default; to display it you must explicitly set thinking.display: "summarized" |
| Tokenizer | Legacy tokenizer | Uses the new tokenizer; the same text yields roughly 1x ~ 1.35x more tokens. It is recommended to raise max_tokens and re-evaluate costs |
Unchanged capabilities: 1M context window, 128k max output, Prompt Caching, Batch API, Files API, PDF / Vision, and the full set of tool calls.
Quick migration checklist: ① Change the model name to
claude-opus-4-7→ ② Remove temperature/top_p/top_k → ③ Replace the thinking parameter → ④ Re-evaluate max_tokens.
5. Friendly Reminders
- If you have higher requirements for performance and stability, we recommend prioritizing the x4 / x6 channels
- For everyday use and cost-sensitive scenarios, the x2.5 Smart Selection Channel is recommended for the best value
